Q

vacuole

A

storage area in the cell

17
Q

lysosome

A

digest wastes and worn-out cell parts, “cleans” the cell

18
Q

chloroplast

A

contain a chemical called chlorophyll (absorbs the sun’s energy & makes the plant green) and allows the plant to make food for itself (like solar panels)
*does photosynthesis
*only in plants

19
Q

cell wall

A

outer boundary of plant cell, rigid & tough, provides support and shape
-made of cellulose
*only in plants

20
Q

prokaryotic

A

cells that do not have a nucleus, usually unicellular

21
Q

eukaryotic
